On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.
"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs." --San Antonio Express-News
Capitalism in space: The private company ArianeGroup has now gotten the okay from the European Space Agency (ESA) to begin full development of its new Prometheus rocket engine, intended to reduce costs 10x.
By applying a design-to-cost approach to manufacturing Prometheus, ESA aims to lower the cost of production by a factor of ten of the current main stage Ariane 5 Vulcain 2 engine. Features such as variable thrust, multiple ignitions, suitability for main and upper stage application, and minimised ground operations before and after flight also make Prometheus a highly flexible engine.
This Prometheus precursor runs on liquid oxygen–methane which brings high efficiency, allows standardisation and operational simplicity. Methane propellant is also widely available and easy to handle.
Essentially, ArianeGroup is going to try to build its own methane-powered rocket engine, having seen the success that SpaceX has so far had with its own Raptor methane engine. This also signals an increased recognition at ESA and ArianeGroup that their new Ariane-6 rocket, whose first launch is still about a year away, is not going to be competitive with SpaceX’s offerings, and needs to be upgraded or replaced.
We are now in the third week of my annual July fund-raiser for Behind the Black. My deep thanks to everyone who has so far donated or subscribed. The response this year has been wonderful.
We are not done yet. This monthly fund-raiser is now half over, and I am hoping the second half will result in as many donations as the first half did. If it does, I will remain free to continue my writing as I see fit, unblemished by the efforts of others to squelch my perspective in this increasingly intolerant world.
This year's fund-raising drive is also significant in that it celebrates the 10th anniversary of this website's founding. It is hard to believe, but I have been doing this for a full decade, during which I have written more than 22,000 posts, of which more than 1,000 were essays and almost 2,600 were evening pauses.
Therefore, I hope you will please consider donating to Behind the Black, by giving either a one-time contribution or a regular subscription, as outlined in the tip jar below. Your support will allow me to continue covering science and culture as I have for the past twenty years, independent and free from any outside influence.
Regular readers can support Behind The Black with a contribution via paypal:
If Paypal doesn't work for you, you can support Behind The Black directly by sending your donation by check, payable to Robert Zimmerman, to
